Gson Formatting

I am using Gson for the settings file of my project. Currently, i'm using the gson.toJson(settings) method. Is there any way to get this to return as a string-array or something so that I can write it multi line? I would like to make it more readable by the end user.

If you can show the java code involved, we could help you.

Code :

---

...
public void saveSettings(){
   Gson gson = new Gson();
   BufferedWriter writer = null;
		try {
			writer = new BufferedWriter(new FileWriter(configFile));
			if(configFile.exists()){
				configFile.delete();
			}
			writer.write(gson.toJson(settings/*is a class*/));
			writer.close();
		}catch(Exception e){
 
		}
}
...

which produces JSon but all in one line. Is there a way around this? Or would I have to make a custom writer/parser?

Quote:

---

gson.toJson(settings/*is a class*/));

Are you asking how to change the contents of what is returned by the toJson() method?
If you know the format of the String(I assume its a String) you should be able to reformat it the way you want.

Sorry to bump, but I've recently started up on the project again. I ended up starting over as the gui didn't scale -_- (forgot about that)

My new save method

Code :

---

...
protected void saveSettings(){
		try{
			File oldFile = new File(settingsFile.toString() + ".old");
			if(oldFile.exists()){
				oldFile.delete();
			}
			settingsFile.renameTo(oldFile);
			Gson constructor = new Gson();
			BufferedWriter out2 = new BufferedWriter(new FileWriter(settingsFile));
		    out2.write(constructor.toJson(settings));
		    out2.close();
		}catch(Exception ex){
			cout.err("Unable to write settings file!");
			ex.printStackTrace();
		}
	}
...

Would churn out this atm:

I'm trying to make it more user friendly for a user to manually edit it if needed. Is there anything built into Gson (or realitvely easy to add) to make it more along the lines of:

Code :

---

{
   "REPOSITORIES":
      {
        "Test Repository":"http://dl.dropbox.com/u/1650058/test.repo",
        "Test 2":"http://dl.dropbox.com/u/1650058/test.repo"
      },
   "checkForUpdates":false,
   "warnBadLinks":true,
   "autoRefresh":false,
   "refreshRate":182601,
   "MCNN_VERSION":"0.8-beta",
   "SETTINGS_FILE_VERSION":"3",
   "REPO_FILE_VERSION":"2"
}

I'm thinking about manually adding System.getProperty("line.separator") after each "," but that wouldn't work for every case, and it wouldn't handle indentation. It's not critical to my program (it functions fine now), but again, trying to add polish to it.
